+
+# minishell
+
+## Description
+
+Minishell is a simplified shell implementation written in C, inspired by bash. The goal of this project is to understand how a real shell works by building one from scratch: parsing user input, managing environment variables, handling redirections and pipes, and executing commands.
+
+Key features include:
+
+- Interactive prompt with command history (GNU readline)
+- Tokenization and parsing of shell commands into an AST (Abstract Syntax Tree)
+- Pipes (`|`) and redirections (`<`, `>`, `>>`, `<<`)
+- Environment variable expansion (`$VAR`, `$?`)
+- Quote handling (single and double quotes)
+- Here-documents (`<<`)
+- Built-in commands: `echo`, `cd`, `pwd`, `export`, `unset`, `env`, `exit`
+- Signal handling (`Ctrl+C`, `Ctrl+D`, `Ctrl+\`)
+
+## Instructions
+
+### Prerequisites
+
+- Docker (recommended for building and running)
+- Or: GCC, Make, GNU readline library
+
+### Build and Run
+
+The recommended way to build and run is inside the Docker environment:
+
+```bash
+# Enter the Docker container
+make docker
+
+# Build inside the container
+make
+
+# Run the shell
+./minishell
+```
+
+### Other Make Targets
+
+| Command         | Description                                      |
+|-----------------|--------------------------------------------------|
+| `make`          | Build the project                                |
+| `make re`       | Clean rebuild                                    |
+| `make clean`    | Remove object files                              |
+| `make fclean`   | Remove object files and binary                   |
+| `make norm`     | Run norminette style checker                     |
+| `make valgrind` | Rebuild and run with valgrind for leak detection  |
+| `make test`     | Run norminette + valgrind                        |
+
+### Usage Examples
+
+```
+$ ./minishell
+minishell$ echo hello world
+hello world
+minishell$ ls -la | grep Makefile
+-rw-r--r--  1 user  staff  2048 Apr 10 12:00 Makefile
+minishell$ export FOO=bar
+minishell$ echo $FOO
+bar
+minishell$ cat << EOF
+> hello
+> world
+> EOF
+hello
+world
+minishell$ exit
+```
+
+## Architecture
+
+The shell follows an interpreter pipeline:
+
+```
+Input -> tokenize() -> heredoc() -> variable_expand() -> remove_quotes() -> parse() -> AST -> execute
+```
+
+1. **Tokenizer** -- State-machine-based lexer that splits input into tokens at operator, space, and quote boundaries.
+2. **Variable Expansion** -- Expands `$VAR` syntax while respecting quote context.
+3. **Quote Removal** -- Strips quote characters from expanded tokens.
+4. **Parser** -- Recursive descent parser that produces a binary AST with `PIPE` (internal) and `CMD` (leaf) nodes.
+5. **Executor** -- Walks the AST, sets up pipes and redirections, and executes commands via `fork`/`execve`.
